A Case of Rahnella aquatilis Bacteraemia After the Receipt of an Unlicensed Intravenous Vitamin Infusion, the First to be Reported in the UK.

Rahnella aquatilis is a Gram-negative bacterium commonly found in the environment. Previously associated with food spoilage, it has in the past been responsible for causing infection in humans, usually as an opportunistic pathogen. We report a case of a previously healthy female who was diagnosed with R. aquatilis bacteraemia. Careful history-taking confirmed she had received an intravenous infusion of presumed-contaminated vitamins immediately prior to presentation. As the global beauty-industry continues to expand, we should be vigilant of future similar cases.
